Answer:


Explanation:
m = Mass of automobile = 1100 kg
v = Velocity of car = 120 km/h = 
h = Height of hill = 80 m
g = Acceleration due to gravity =

Change in kinetic energy is 
Change in potential energy is given by

The change in potential energy is
.
Answer:
32 horsepower will be equal to 17600 ft-lb/sec
Explanation:
We have given 1 horsepower = 550 ft-lb/sec
We have to convert 32 horsepower into ft-lb/sec
As we know that 1 horsepower is equal to 550 ft-lb/sec
So for converting horsepower to ft-lb/sec we have multiply with 550
We have given 32 horse power
So 
So 32 horsepower will be equal to 17600 ft-lb/sec
Answer:
Technician B only is correct
Explanation:
Voltage drop testing is a method used to find the amount of electrical resistance available in an high amperage circuit that involves connecting the leads of the meter in parallel to the circuits being tested such that disassembly is not required
In voltage drop test, the red voltmeter lead and black voltmeter lead are placed at two points on the same side of the circuit connection such that the leads are in between two positive connection or two negative connection (rather than connecting the red to the positive and the black to the negative sides of the circuit) and digital voltmeter is used for the voltage drop measurement across the lead while the connection is under load.
Therefore, Technician B only is correct
